PROCESS OF MAKING A NONMETALLIC LACE Application filed April 5, 1928.Serlal'll't). 630,134.

To all whom it may concern I Be it knownv that; 1", Chat. A. MArsoN, acitizen of the United States, and resident of Lynnfield, in the countyof Essex and State 5 of Massachusetts, have invented an Improvement inProcess of Making a Nonmetallic Lace Tip, of which the followingdescription, in connection with the accompanying drawings, is aspecification, like letters on the drawings representing like parts.

My present invention is a novel, and improved tipped lace made by anovel process, and consists in the treatment of the lace end or part tobe tipped, by moldable material, such as is employed in the making of aso called fabrictip and then treating, .compresing orotherwise moldingand forming the treated portion to simulate a metallic tipped lace.

In the art of tipping laces, particularly shoe laces, corset laces, andother lacings for use in clothing, it has heretofore been cu's tomary toapply ametal blankabout the end or portion of the lace intended to betipped,

25 or to treat the lace by impregnating or otherwise applying a suitablesubstance, composition orthe like, which when dried, set or hardened,would stiffen-the lace sufficiently to constitute a rigid or tippedportion.

In my development of the art of lace tipping, I have devised novel andefficient tipping machines, such for example as that shown by my priorand copending applica tions Ser. Nos. 379,734, filed May 8, 1920;592,814, filed October 6,1922; 610,142, filed January 2, 1923; and Ihave also devised novel methods, as well as material'for use in lacetipping, preferably such as is shown in my copending applications Ser.Nos. 474,253, filed June 1,1921; and 610,141, filed January 2, 1923. Ifind that it. is possible and feasible to utilize non-metallic. materialfor lace ti ping, which will result in a completed article ofmanufacture substantially similar in ap earance to certain metallictipped laces. urthermore, by means of my machines and processes, I canproduce such a non-metallic lace tip much more economi- Cally at greatspeed in production, and very simply and most efiiciently with a highdegree of uniformity in the resulting product resembling metalliccorrugated lace t1pp1ug. Furthermore, such resulting article, v1z., a

'laceof usua non-metallic corrugated lace tip, is more satisfactory inuse anddesirability from the wearers standpoint. I believe that myinvention and process, whereby a non-metallic lace tip, particularly acorrugated non-metallic lace tip, can thus be made to resemble ametallic lace tip, and even a corrugated metallic lace tip, is adistinct novelty in this art, and I wish to claim these features ad y.

Referring to the accompanying drawings illustrating my improved type ofnon-metallic tipped laceand showing the preferred process of makingsame, 7

F ig; 1 is a fragmentary plan view of a portion of'a lace to be tipped;

Fig. 2 is a view of the lacing after the non-metallic materialisapplied;

Fig. 3 illustrates the completed lace; A

Fig. 4 is a cross-sectional view on the line 44ofFig.3;and

Fig. 5 is a cross-sectional view on the line 55ofFig.3.

While I have hereinillustrated a single end or end portion of a lace,and the tipping material applied thereto, it will be understood that Ican, and preferably will, pro duce the presenttipped lace by making samein a machine, s uch for example as that shown in my application Ser; No.592,814, wherein a double lengthpfa lace to be tipped ;i. e i a lengthsuflicient for two end tips ;Y'i's treated and molded simultaneously,this double length being severed or cut to form the two end tips of thelace. It is, however; possible and feasible to produce the presenttipped lace by other machines and processes or the like. Furthermore in'the attached drawings I have illustrated the present in: vention asapplied to a tubular braided form although it is feasible to produce mynon-metallic tipped lace from flat braid used in manufacturing tippedlacing if desired.

As shown in Fig. 1, the lacing 1 is of suitable size and desired color,of tubular form, is supplied and may be drawn from a roll, asillustratedin my said prior patents, a predetermined portion of.

the lacing being treated as indicated in Fig. 2, with a mass of moldablematerial. Preferably this moldable mater al s applied to the lacing in apartially l1qu1d or mobile state, being in proper form to adhere to theand customary commercial and preferably plied to lacing, preferably toimpregnate the fibers of the lacing, and to constitute a suitable mass,which when dry or set, will retain its final form. This material, if ofcelluloid or of'a composition, such for example as eration.

Heretofore such molding operation on fabric tipped laces has beeneffected by means of a plain compressing die. The resulting product,however, would not resemble a metallic tipped lace. In my presentinvention, therefore, I subjected the treated lac-e portion to acorrugated die. which will result in producingan equivalent corrugatedstructure on the treated lace end, thus simulating almost exactly andwith even greater uniformity than is possible in metallic tipped work, ametallic type of lace tip. It will be appreciated. that in theapplication of metallic blanks to lace tips, it is frequently necessaryand indeed customary to form one or more corrugations on the metal, orindentations or the like, which tend to grip or clamp the metal morefirmly into the lace material. Thus the public are quite familiar withthe corrugated metal tipped lace, and in my present process I simulatethis corrugated metal tipped lace, but by making a non-metallic tippedlace. As shown in Fig. 3, the resulting molded fabric tipped or nonmetallic tipped material, produces a series of corrugations orconvolutions, having alternate convexed portions 3 and concave sectionsat. This extra compression given to the treated end in the formation ofthe corrugated tip, produces a high degree of compression and presents afinished surface very closely approximating in gloss and finish, ametallic tip of similar contour.

My corrugated non-metallic tipped lace claimed herein is also thesubject-matter of my design application. Ser. No. D5437, filed March 12,1923.

My invention is further described and defined in the form of claim asfollows:

The process of making a non-metallic tipped lacing, having a corrugatedcontour, which consists in applying to a predetermined portion of thelacing, moldable material in plastic form, and thereafter molding saidtreated portion into corrugated form.

In testimony whereof, I have signed my name to this specification.

CARL A. MATSON.
